Abstract
The invention relates to a device for opening and closing a movable furniture part, in particular a drawer, door or shutter. The device comprises according to the invention two trigger and drive units which each have a trigger member controllable by the action of an external force and a drive member coupled to the trigger member for moving the furniture part and at least one locking member for locking the furniture part in the closed position and release of the furniture part as a function of the action of an external force on at least one trigger member, wherein the two trigger/drive units are coupled to one another synchronously and substantially without play by path- and force-transmitting means.
Claims12
Device for opening and closing a movable furniture part, in particular a drawer, door or shutter, characterised by
- two trigger and drive units (6) which each have a trigger member controllable by the action of an external force and a drive member (8) coupled to the trigger member for moving the movable furniture part (3) and
- at least one locking member (17) for locking the furniture part (3) in the closed position and release of the furniture part as a function of the action of an external force on at least one trigger member (6), wherein the two trigger and drive units (6) are coupled to one another synchronously and substantially without play by path- and force-transmitting means (16).
Device according to one of the preceding claims, characterised in that each trigger and drive unit (6) comprises a disengaging lever (8) mounted rotatably directly or indirectly on the movable furniture part and acted upon by a spring (10) which lever acting in conjunction with a limit stop (2) arranged in fixed position on the furniture carcass (1) determines the closed and open position of the movable furniture part (3).
Device according to one of the preceding claims, characterised in that in the closed state of the movable furniture part one end of the disengaging lever (8) rests against the limit stop (2) of the furniture carcass (1).
Device according to one of the preceding claims, characterised in that the initial tension of the spring (10) is adjustable.
Device according to one of the preceding claims, characterised in that the disengaging lever (8) is constructed in the form of a guide bar possessing at least two legs (11;
- 14) whose first leg (11) forms the trigger member and whose second leg (14) is coupled via at least one path- and force-transmitting connecting member (16) to the second leg (14) of the respective other disengaging lever.
Device according to one of the preceding claims, characterised in that the locking member comprises a spring-loaded latch (17) temporarily actively connected to one of the two trigger/drive units (6).
Device according to one of the preceding claims, characterised in that the end of the first leg (24) of the disengaging lever is constructed like a fork and acts in conjunction with a limit stop constructed in the form of a pin (25) in fixed position.
Device according to one of the preceding claims, characterised in that the trigger/drive unit (6) and the locking member (17) are arranged on a common assembly panel (7) to be fastened to the movable furniture part (3).
Device according to one of the preceding claims, characterised in that on the disengaging lever (8) an adjusting device is provided by means of which the position of the first leg (27;
- 37) is alterable relative to the position of the second leg (28;
- 40).
Device according to one of the preceding claims, characterised in that means (54, 56) for limiting the movement of the furniture part (3) brought about by the trigger and drive unit (6) are provided.
Device according to one of the preceding claims, characterised in that the means (16) for path- and force-transmission are mechanical, electromechanical, pneumatic or hydraulic means.
